Notes

From email: "We suspect this happened fresh today, we  wonder if those animal tracks coming in from the left triggered it. North facing, 2 ft crown, (I’d guess), about 9k feet, facing Goose Creek. So our friends (while ski cutting) triggered a  very similar slide on this same aspect/elevation mid afternoon today, about 1/4 mile farther west along this ridge, looked to be same depth."
